dashed vertical line through (0, −15) with shading to left of line
(15, 2)
dashed horizontal line through (0, −15) with shading above line

Answer:

  False

Step-by-step explanation:

You want to know if it is true that the graph of a rational function cannot cross a horizontal asymptote.

Once a function is on its final approach to an asymptote, it will approach, but not cross, that asymptote.

The function may have a variety of behaviors prior to that point, so may cross the horizontal asymptote one or more times before its final behavior is established.

An example with the asymptote y = 0 is attached.

The values of A and B are -2 and 3 respectively, the line 2x - 3y = 6 is equivalent to the line x = 3.

To find the values of A and B, we can substitute the coordinates (0, A) and (B, 0) into the equation 2x - 3y = 6.

For the point (0, A):

2(0) - 3(A) = 6

0 - 3A = 6

-3A = 6

A = -2

So, A = -2.

For the point (B, 0):

2(B) - 3(0) = 6

2B = 6

B = 3

So, B = 3.

Therefore, the values of A and B are A = -2 and B = 3.

b) Now that we know the values of A and B, we can substitute them into the equation 2x - 3y = 6:

2x - 3y = 6

2x - 3(0) = 6 (substituting y = 0)

2x = 6

x = 3

So, the line 2x - 3y = 6 is equivalent to the line x = 3.

if both the antibody screen and the indirect Coombs test are negative, fetal DNA testing may not be necessary, as there is no evidence of sensitization to Rh antigens.

Step-by-step explanation:

If an Rh-negative pregnant woman has produced anti-D antibodies, fetal DNA testing is recommended to determine whether the fetus is Rh-positive or Rh-negative. The recommended second step depends on the test results of the indirect Coombs test and the antibody screen.

If the antibody screen is positive, and the indirect Coombs test shows increasing levels of anti-D antibodies, fetal DNA testing is recommended as the next step.

If the antibody screen is negative, but the indirect Coombs test shows increasing levels of anti-D antibodies, fetal DNA testing is also recommended.

There are likely to be 190 elk infected with the parasite in the population of 4,750 elk at the wildlife preserve.

Now, To estimate the number of elk that are likely to be infected, we can use the sample proportion of infected elk to the total population of elk.

Hence, The sample proportion of infected elk is,

⇒ 2/50 = 0.04.

We can use this proportion to estimate the proportion of infected elk in the entire population of ;

4,750: 0.04 = x/4750

Solving for x, we get:

Answer:

The sheet should be turned up 7.5cm on each side to obtain maximum volume.

Step-by-step explanation:

If we make a rectangular eavesdrop, by bending the sheet along dotted line, then.

Height of eaves trough = x cm

Length of eaves trough = 600 cm

Width of eaves trough =  (30 - 2x) cm

We know that Volume is given by:

V = Length · Width · Height

V = (x)(30 - 2x)(600)

V = -1200x² + 18000x

To maximize the volume, we take the derivative and put it equal to zero.

\(\frac{dV}{dx} =\frac{d}{dx}( -1200x^2 +18000x)=0\\\frac{d}{dx}( -1200x^2 +18000x) = 0\\-(2)1200x+18000=0\\-2400x+18000=0\\x=\frac{18000}{2400}\\ x=7.5cm\)

The correct answer is B. The graph of h is the graph of g vertically shifted up 1 unit.

The correct answer is:

B. The graph of h is the graph of g vertically shifted up 1 unit.

Explanation:

The original function g(x) = x² represents a basic quadratic function, which is a parabola that opens upward and has its vertex at the origin (0, 0).

When we consider the function h(x) = g(x) + 1, we are adding a constant value of 1 to the output (y) values of the function g(x). This results in a vertical shift of the graph of g(x) by 1 unit upward.

In other words, for every x-value, the corresponding y-value of the function h(x) will be 1 unit higher than the corresponding y-value of the function g(x).

Visually, this means that the graph of h(x) will be the same shape as the graph of g(x), but it will be shifted upward by 1 unit. The vertex of the parabola, which was originally at the origin, will now be at (0, 1).

The statement "The graph of h is the graph of g horizontally shifted left 1 unit" (Option A) is incorrect because there is no horizontal shift in this transformation.

The statement "The graph of h is the graph of g vertically shifted down 1 unit" (Option B) is incorrect because the transformation results in a vertical shift upward, not downward.

The statement "The graph of h is the graph of g horizontally shifted right 1 unit" (Option D) is incorrect because there is no horizontal shift in this transformation.

Therefore, the correct answer is B. The graph of h is the graph of g vertically shifted up 1 unit.

The type of sampling used in this scenario is B. Stratified sampling. Stratified sampling involves dividing the population into distinct subgroups or strata and then selecting samples from each subgroup.

In this case, Miranda divides her day into three parts: morning, afternoon, and evening. Each part of the day represents a stratum or subgroup.  Miranda measures her breathing rate at 4 randomly selected times during each part of the day. This means she is taking samples from each of the three strata (morning, afternoon, and evening) and collecting data from within those subgroups.

By using stratified sampling, Miranda ensures that her samples represent the different parts of her day in a proportional and systematic manner, allowing her to capture potential variations in her breathing rate throughout the day.

since you know the negative sign would turn to a positive sign when they multiply each other.

and be mindful of problems with different signs like

−6×9, you'll definitely get a negative answer

Now to your question.

(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form

since it's -5 raised to the power of 3

you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations

if you do it correctly, you'll arrive at the answer

The probability that the sample mean will be greater than 57.95 is 0.0495.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. This is the basic probability theory, which is also used in the probability distribution.

To solve this question, we need to know the concepts of the normal probability distribution and of the central limit theorem.

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z=\dfrac{X-\mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The Central Limit Theorem establishes that, for a random variable X, with mean \(\mu\) and standard deviation \(\sigma\), a large sample size can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(\frac{\sigma}{\sqrt{\text{n}} }\).

In this problem, we have that:

The probability that the sample mean will be greater than 57.95

This is 1 subtracted by the p-value of Z when X = 57.95. So

\(Z=\dfrac{X-\mu}{\sigma}\)

By the Central Limit Theorem

\(Z=\dfrac{X-\mu}{\text{s}}\)

\(Z=\dfrac{57.95-53}{3}\)

\(Z=1.65\)

\(Z=1.65\) has a p-value of 0.9505.

Therefore, the probability that the sample mean will be greater than 57.95 is 1-0.9505 = 0.0495

The smallest sample size n that provides the desired accuracy is 10.

To find the smallest sample size n that provides the desired accuracy, we can use the formula:

n = (Z-value * standard deviation / margin of error)²

Where:
Z-value = the critical value for the desired confidence level (in this case, 1.96 for 95% confidence)
Standard deviation = the preliminary sample standard deviation (1.5 in this case)
Margin of error = the desired accuracy (0.3 units in this case)

Substituting the values, we get:

n = (1.96 * 1.5 / 0.3)²
n = 9.8

Since we cannot have a fractional sample size, we round up to the nearest whole number, giving us:

n = 10

Therefore, the smallest sample size n that provides the desired accuracy is 10.

Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

To determine when tan(theta) is undefined on the unit circle, we need to remember the definition of the tangent function.
Tangent is defined as the ratio of the sine and cosine of an angle. Specifically, tan(theta) = sin(theta)/cos(theta).

Now, we know that cosine can never be equal to zero on the unit circle, since it represents the x-coordinate of a point on the circle and the circle never crosses the x-axis. Therefore, the only way for tan(theta) to be undefined is if the cosine of theta is equal to zero.
There are two values of theta on the unit circle where cosine is equal to zero: pi/2 and 3pi/2.

At theta = pi/2, we have cos(pi/2) = 0, which means that tan(pi/2) = sin(pi/2)/cos(pi/2) is undefined.
Similarly, at theta = 3pi/2, we have cos(3pi/2) = 0, which means that tan(3pi/2) = sin(3pi/2)/cos(3pi/2) is also undefined.
Therefore, the answer is option C: theta = pi/2 and theta = 3pi/2.

The period of the voltage signal V(t) = 10 sin(t) is 2π because the sine function has a natural period of 2π and the coefficient of t does not affect the period in this case.

To find the period T of the voltage signal V(t) = 10 sin(t), we can use the properties of the sine function.

The sine function has a period of 2π, which means it repeats itself every 2π units. In the given equation V(t) = 10 sin(t), the coefficient of t is 1, which means the period is affected by the coefficient.

In this case, the voltage function has a coefficient of 1, so the period T can be found by equating 2π to the coefficient multiplied by the period:

2π = 1 * T

Simplifying the equation, we have:

T = 2π

Therefore, the period T of the voltage signal is 2π.

The probability of rolling a 5 is 0.1.

To find the missing probability for rolling a 5, we can use the fact that the sum of all probabilities for all possible outcomes must equal 1.

Let's calculate the missing probability:

1. Sum the probabilities of the given outcomes: 0.1 + 0.2 + 0.3 + 0.2 + 0.1 = 0.9.

2. Subtract the sum from 1 to find the missing probability: 1 - 0.9 = 0.1.

Therefore, the missing probability for rolling a 5 is 0.1 or 10%.

Here are the steps summarized:

1. Calculate the sum of the given probabilities: 0.1 + 0.2 + 0.3 + 0.2 + 0.1 = 0.9.

2. Subtract the sum from 1 to find the missing probability: 1 - 0.9 = 0.1.

This approach ensures that the probabilities for all possible outcomes in the probability distribution add up to 1, as required. In this case, the sum of all probabilities is 0.9, so the missing probability for rolling a 5 is the remaining 0.1 or 10% needed to reach a total probability of 1.

Since, (3x + 14 - x + 112) = (3x - x) + (12 + 112)

                                      = 2x + 124

Therefore, (3x + 14 - x + 112) ≠ (4x + 134) [Not equivalent]

Option 2

(2 + 6x) and 2(3x + 1)

                                  = 4x + 2

Therefore, (2x + 3) ≠ (4x + 2) [Not equivalent]

Option 4

3x and 4(x + 1) - x - 4

Since, [4(x + 1) - x - 4] = 4x + 4 - x - 4

                                   = (4x - x) + (4 - 4)

                                   = 3x

Therefore, 3x = [4(x + 1) - x - 4] [Equivalent]

Option 5

(5.5 + 2.2x + 3.8x - 4.1) and (1.4 + 6x)

Since, (5.5 + 2.2x + 3.8x - 4.1) = (2.2x + 3.8x) + (5.5 - 4.1)
